Seeing as these were 30% of at Cyclesurgery got a pair to replace some hummvee's...

Still expensive - but after an initial ride very impressed...
1. the ergosnap sounds like bullshite, but the short and the liner stay together without loops or poppers
2. the liner is super comfy (seamless) and the pad very dense and shaped i.e. not squishy with your fingers (why do people test thing like shoes etc with fingers...) so not pressure points felt.
3. The shorts fit nice and do not have many zips etc just two simple zipped pockets
The liners is a bit odd, sort of the b@stard child of some ladies opaque tights and fishnet stockings.... 
Pro's
Liner and short stay together without clips or poppers
Cut is very good for cycling
Liner and Pad is supper comfy
If you an ardent follow of the rocky horror show then you will have an extra item of clothing to add to your show outfit
Con's
Expensive
Still not as comfy as Bib shorts
Worry that someone will see you just in the liners.....
New Hummvee Lites seems a good new option as well.. simpler and lighter than singletracks or ordinary hummvee's
